A method for pseudo channel hopping in a node of a wireless mesh network is provided that includes scanning each channel of a plurality of channels used for packet transmission by the node, wherein each channel is scanned for a scan dwell time associated with the channel, updating statistics for each channel based on packets received by the node during the scanning of the channel, and changing scan dwell times of the plurality of channels periodically based on the statistics.

The present invention relates to a method and apparatus for transceiving data. A method in which a transmitting terminal transmits data to a receiving terminal in a MIMO system according to one embodiment of the present invention comprises the following steps: generating a data field containing the data; generating a signal field containing information on the data field; generating a data frame containing the data field and the signal field; and transmitting the data frame to the receiving terminal. According to the present invention, an end of the frame being transmitted is accurately notified to the receiving terminal in a communication system in which the frame is transmitted using MIMO, thereby decoding the frame in a more efficient manner at the receiving terminal.

Techniques are described for wireless communication. One method includes detecting a first reference signal received from a user equipment (UE) in a reference scheduled transmission burst including a plurality of contiguous transmission time intervals (TTIs) received over a shared radio frequency spectrum band; identifying a reference TTI in which the first reference signal is received; determining a contention window size usable by the UE to contend for access to the shared radio frequency spectrum band; and transmitting an indication of the determined contention window size to the UE.

A control information utilization method and an apparatus of a terminal with heterogenous technology communication modules operating in a same frequency band are provided to protect against unnecessary battery power consumption. A control information reception method of a terminal includes receiving control information from a base station using a first module, determining a channel occupancy time based on the control information using a licensed assisted access (LAA) radio identifier, and transferring the channel occupancy time to a second module that is operating in a same frequency band as the first module.

Various embodiments disclosed herein provide for multi-stage segmentation of downlink control information. Downlink control information can arrive at a user equipment on more than one channel, setting up and configuring data channels for different base stations, or data channels for the same base station but where the data channels are in different frequency domains or time domains. The downlink control information segmentation system disclosed herein can determine when downlink control information for the user equipment is common across a plurality of downlink control channels, and ensure that the downlink control information is sent just one time, to avoid redundant data transmissions and increased overhead.
